Thank you very much ...... unfortunately the MK II cannot play without a crossover, it will take about 1 week. Then I will know if I will be rewarded by my queen for this innovation, the time and financial expense of mine. I think I am currently building the most beautiful and best sounding RF 7 MK II in the world. A prototype and unicat. If there is someone else, e.g. there is a similar project in America that I would like to get to know. I don't know anyone yet, neither in Germany nor in Europe. 😇 Best regards MicroMara 1 Quote Link to comment Share on other sites More sharing options...

MicroMara Posted February 4, 2020 Author Share Posted February 4, 2020 It goes on step by step ..... The new speaker cables, a total of 8 x 12 mm2 single wire are also in the works..........It looks like a Tag McLaren RF 7...😇 Hold you up to date.........

MicroMara Posted February 6, 2020 Author Share Posted February 6, 2020 Hi Guys...... I had to schedule my project. Before I could finish the external crossover, I had to have all the cable sets, i.e. 8 x 12 mm2, each 52 inches long. My speaker cables are all DIY. It makes no sense to finish the external crossover first and then start with the cable layer. This naturally delays the work on the external crossover by 1 week. I only work on them if I have enough concentration in the evening, I'm in a bad mood, then I prefer not to do anything. Quality and perfection are my top priority. In Germany we say .... Good things take time. Here you can see how I make my speaker cables. See you soon 😎 Best regards MicroMara 2 Quote Link to comment Share on other sites More sharing options...

glens Posted February 7, 2020 Share Posted February 7, 2020 Do those connectors have an internal wedge that expands them once they're inserted? 1 Quote Link to comment Share on other sites More sharing options...

MicroMara Posted February 7, 2020 Author Share Posted February 7, 2020 11 hours ago, glens said: Do those connectors have an internal wedge that expands them once they're inserted? Yes, the screw head has a mandrel that spreads apart when screwed into the pole terminal. This guarantees maximum contact area and contact stability. These connectors are a low-mass principle with OFC copper signal conductors. To protect against oxidation, it is directly gold-plated without nickel. This maintains its high conductivity and is free from magnetic interference. The contact pin is shaped in such a way that its three segments 'bulge' by screwing in the spindle and it can be firmly clamped in each pole terminal. The resulting constant high contact pressure guarantees consistently low contact resistance. Thanking you very much for your kind attention Mr. Glens......

MicroMara Posted February 16, 2020 Author Share Posted February 16, 2020 just a quick update. I'm about to finish my project with the external crossover for my RF7 MK II Queen. I have already carried out a first test setup. I have to make some internal crossover wireing changes before the whole concept can be completed. You will find out more details in two or three days.This is a picture of the first test setup, the crossovers are located on the left under the tape machine and on the right under the turntable.Further details coming a.s.a.p.

MicroMara Posted February 16, 2020 Author Share Posted February 16, 2020 The small wiring errors I caused on the new external crossover itself have been eliminated. It went faster than I thought because I had support from a good friend who had helped me to fix it today. It was done in two hours and the external crossovers are now working propNow you see the first pictures of the new crossover. A conventional crossover has a circuit board on which the resistors, coils and capacitors are installed. With a freehand wired crossover, the components are usually attached to a base plate and connected to the inputs / outputs a conventional cable wiring to the speakers. My crossover is, let's call it "negative replica" of a switch, the solution is another. All components are installed in a housing on the base plate. There are 4 OFC copper power lines above the components. These are directly connected to the inputs / outputsAll coils, resistors and capacitors are directly connected to these "live cables". This is the shortest and most direct way imaginable. It works like a "power substation". On the ground, the customers are in the air hanging the lines. The potential of all components is thus fully exploited.. All coils, resistors and capacitors are directly connected to these "live cables". This is the shortest and most direct way imaginable. It works like a "power substation". On the ground, the customers are in the air hanging the lines. That is my basic idea for the development of the new crossover. Therefore the large housing. The potential of all components is thus fully exploited.At least that is my opinion........ 2 Quote Link to comment Share on other sites More sharing options...
